WILLIAM H. OLIVER, OF CHICAGO, ILLINOIS.

WRENCH OR NUTJACK.

Specification of Letters Patent.

Patented Feb. 18,1908.

Application filed September 22. 1906. Serial No. 335705.

To all whom it may concern:

Be it known that I, WILLIAM H. OLIVER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Wrenches or N ut-J acks, of which the following is a full, clear, and exact specification.

This invention relates to improvements in wrenches or nut jacks, as they are sometimes designated, and the primary object of the invention is to produce an improved device of this character which may be easily and quickly adjusted, and locked in its adjusted position; the locking means serving also as a means for securing a still further or finer adjustment.

A further object is to produce an improved device of this character which will be simple, durable and cheap in construction and efficient in operation. I

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating an exemplification of the invention, and in which:

Figure 1 is a side elevation of a wrench or jack constructed in accordance with the principles of this invention; Fig. 2 is a longitudinal sectional view on line 22 of Fig. 3 Fig. 3 is a detail rear elevation of Fig. 1; Fig. 4 is a detail rear elevation of a portion of the shank or body of the wrench; Fig. 5 is a sectional view on line 55 of Fig. 2; Fig. 6 is a detail of the adjusting member and cam; Fig. 7 is a top plan view of the movable jaw and collar or sleeve.

In this exemplification of the invention, the numeral 10 designates the shank or body of the wrench, on one end of which is an outer rigid jaw 11, the other end 12 being shaped to form a suitable handle. The shank 10 is preferably angular in form and of any desired shape, and is provided on its rear face with spaced longitudinal projecting parallel ribs 13-14, which are located preferably remote from the sides of the body of the shank and terminate short of the end thereof. The rib 14 is slightly higher than the rib 13 and is provided with a series of teeth constituting a rack. The shank 10 is recessed or grooved as at 15 between the ribs 13-14 and adjacent the lower ends thereof to form a shoulder 16, and below the adjacent ends of the ribs the shank or body is channeled out or depressed so that the adjacent end of the groove 15will be open. Located within the channeled or depressed portion of the shank, and in a direct line with the groove 15, is a lug or stop 17.

The above described parts may be formed in any desired manner,.preferably by casting the same, and the aw 11 may be formed with a rounded outer face and an angular in nor face 18; the jaw being preferably disposed at a right angle to the shank.

A sleeve or collar 19 surrounds and slides on the shank 10, and projecting from the end thereof, preferably the end adjacent the jaw 11 is a similar jaw 20, which is arranged at a right angle to the sleeve or collar and parallel with the jaw 11. This jaw is also preferably provided with a rounded outer periphery and an angular inner face 21 corresponding to the angular face 18 of the jaw 11. A portion 22 of the rear wall 23 of the sleeve or collar 19 is spaced from the sides thereof and the shank 10, and said wall is provided adjacent the ends of the spaced portion with alined grooves or recesses 24, adapted to receive the projecting portion of the rib 14. The spaced portion 22 is provided with an a erture 25, preferably disposed in line with t 1e space between the ribs 13 and 14.

A handle 26 is secured to the sleeve or collar 11, preferably adjacent the end opposite to the jaw 11, in any suitable manner, preferably by means of a removable bolt 27 having a threaded end 28, ada ted to extend beyond the inner face of the s eeve or collar 19, and between the lug or projection 17 and the shoulder 16, so that when the sleeve or collar 19 is moved to separate the jaws 21 and 11, the end of the bolt 27 will engage the lug or projection 17 to limit the movement of the sleeve to prevent accidental displacement of the parts, and when moved to close the jaws, the projecting end will enter the space between the ribs 1814 and the groove 15 to permit the jaws to be brought into close proximity. g

A suitable locking and adjusting member is provided for the movable jaw 19, which preferably comprises a body portion 29 provided with a centrally disposed laterally projecting trunnion or lug 30 extending from the outer face thereof, and a similar lug or trunnion 31 extending from the inner face thereof and preferably in alinement with the lug or trunnion 30. Projecting also from the body ortion 29 and beyond the plane of its inner face is a cam shaped rib or fin 32 one end 33 of which terminates adjacent the periphery of the body portion. This member 29 may be provided with a suitable operating handle 34, by means of which the member 29 may be rotated upon the trunnion or projection 30, which latter is adapted to be seated and journaled in the aperture 25 in the spaced portion 22 of the rear wall 23 of the sleeve or collar 19. When thus assembled and with the sleeve or collar 19 surrounding the shank 10 the lug or trunnion 31 will enter the space between the ribs 1314 to prevent lateral displacement of the member 29.

The handle 34 is so arranged as to project beyond the side of the sleeve or collar 19, and when the member 29 is rotated by the handle the cam shaped rib or fin 32 will pass between the teeth on the rib 14 and draw the jaw 20 towards the aw 11 the rotation of the member 29 being limited by the handle 34, engaging the sides of the spaced portion 22.

WVhen the handle 34 1s in a position to cause the cam shaped rib or fin 32 to disengage the teeth on the rib 14, the sleeve or coIlar 19 may be quickly adjusted by moving the same upon the shank 10 until the jaws 21 and 11 have been brought into engagement with the sides of the nut to be adjusted; after which the handle or lever 34 may be moved to rotate the member 29, thereby causing the cam shaped rib or fin 32 to pass between the teeth on the rib 14, which will further adjust the jaw 20 to firmly grip the nut the cam shaped rib or fin being of such a pitch as to lock the sleeve or collar 19 agalnst retrograde movement, when pressure is exerted upon the jaw 20, and when the member 29 is in any of its operative positions.

In order to permit the ready insertion of the member 29 and the lug or trunnion 30 into the aperture 25 in the spaced portion 22 of the wall 23, the sides of the sleeve or collar 19 are cut away or recessed as at 35, prefer ably in line with the aperture 25, to permit the lug or trunnion 31 to pass therethrough. The sides of the sleeve or collar 19 in which the cut away portion or recess 35 is located is preferably of a Width less than the width of the shank 10, so that when the sleeve or collar 19 surrounds the shank, the latter will form a closure for the said recesses 35.

The member 29 may be placed in position in the sleeve or collar 19 before the latter is placed upon the shank 10, if desired, or the sleeve or collar first placed over the handle portion 12 and then the member 29 inserted.

After the handle 26 has passed the lug or projection 17, the bolt 27 may be adjusted to cause its threaded end 28 to project, beyond the inner face of the sleeve or collar and in a position to strike the lug or projection 17 to prevent accidental displacement of the parts.
